AISI ASTM 316 Stainless steel half round bar processing difficulties

In AISI ASTM 316 Stainless steel half round bar stainless steel processing, because the strength of the stainless steel material is large, the tangential stress and plastic deformation are large during cutting, so the cutting force is large. In addition, the material has extremely poor thermal conductivity, resulting in increased cutting temperature and high temperature It is often concentrated in the narrow area near the cutting edge of the tool, which accelerates the wear of the tool.

AISI ASTM 316 Stainless steel half round bar machining and some high-temperature alloy stainless steels are all austenitic structures, which have a large work hardening tendency during cutting, usually several times that of ordinary carbon steel. The tool is cut in the work hardened area, which shortens the tool life.

Whether it is austenitic stainless steel sheet processing or martensitic stainless steel, both have the characteristics of toughness and high cutting temperature during processing. When the tough chips flow through the rake face, sticking, welding, etc. will occur. This phenomenon affects the surface roughness of processed parts. Stainless steel generally contains high melting point elements, high plasticity, and high cutting temperature, which accelerates tool wear, sharpens and changes frequently, which affects production efficiency and increases tool usage costs. This is all Difficulties in stainless steel processing.

In summary, the processing difficulties of AISI ASTM 316 Stainless steel half round bar can be attributed to the large cutting force, high cutting temperature, severe work hardening, easy sticking, and fast tool wear. These major difficulties will affect the efficiency of stainless steel manufacturers in processing stainless steel.
